Hi
Everyday I find new amazing possibilities of Lightburn. Maybe I missed this one…
Is it possible to find the center of gravity of a shape or a closed path?
If not, it would be a nice to have…
EDIT: I found that it exists as an extension of Inkscape (Extensions->Visualize Path->Measure Path? Choose the Measurement Type->Center of Mass.). Maybe this can help you implement it in LB.
